Anybody here know if i could hook it up to my truck. like the prices and if i could do it myself?
is the truck diesel? or do you plan to run it as the main fuel?
www.pirate4x4.com has a write up on it.
http://www.pirate4x4.com/tech/propane/index.html direct link to the article.
Search the boards here too...I know I've discussed it a while back.
What I can tell you is that prices are NOT good. The ACE where I work charges $2.75 a gallon...and that price doesn't fluctuate. /forums/images/graemlins/eek.gif
propane is good in that it can run at any angle... but the fact that not all stations have it, that you have a high pressure gas bomb attached to your rig, and that propane doesnt have nearly the energy per (insert whatever volume unit you want here) as gasoline means you need more of the stuff to get the same performance. Just my opinion, but the negatives out weigh the posetives.

02. INGREDIENTS - COMPOSITION & INFORMATION
PERCENT EXPOSURE GUIDELINES
COMPONENT CAS No. (BY WT.) OSHA - TWA ACGIH - STEL
Propane 74-98-6 99.0% 100.0% 1000 Simple Asphyxiant
LD50: None. LC50: None.
03. HAZARDS IDENTIFICATION
Flammable liquid gas under pressure.
Can form explosive mixtures with air.
May cause frostbite.
Potential Health Effects Information:
Routes of Exposure:
Simple asphyxiant. It should be noted that before suffocation could occur, the lower
flammability limit of propane in air would be exceeded; possibly causing both an
oxygen-deficient and explosive atmosphere. Exposure to concentrations (> 10%)
may cause dizziness. Exposure to atmospheres containing 8-10% or less oxygen
will bring about unconsciousness without warning, and so quickly that the individuals
cannot help or protect themselves. Lack of sufficient oxygen may cause serious
injury or death.
Contact with liquid or cold vapor can cause freezing of tissue.
Contact with liquid or cold vapor can cause frostbite.
Medical Conditions Aggravated By
Other Effects Of Overexposure:
Propane is not listed by NTP, OSHA or IARC.
04. FIRST AID MEASURES
Persons suffering from lack of oxygen should be removed to fresh air. If victim is
not breathing, administer artificial respiration. If breathing is difficult, administer
oxygen. Obtain prompt medical attention.
Contact with liquid or cold vapor can cause freezing of tissue. Gently flush eyes
with lukewarm water. Obtain medical attention immediately.
Contact with liquid or cold vapor can cause frostbite. Immediately warm affected
area with lukewarm water not to exceed 105°F (40°C).
Notes To Physician:
05. FIRE FIGHTING MEASURES
Flammable Limits - Lower:
Flammable Limits - Upper:
CO2, dry chemical, water spray or fog for surrounding area. Do not extinguish until
propane source is shut off.
Fire Fighting Instructions:
Evacuate all personnel from danger area. Immediately cool container with water
spray from maximum distance, taking care not to extinguish flames. If flames are
accidentally extinguished, explosive re-ignition may occur. Stop flow of gas if
without risk while continuing cooling water spray.
Fire And Explosion Hazards:
Propane is easily ignited. It is heavier than air, therefore, it may collect in low areas
or travel along the ground where an ignition source may be present. Pressure in a
container can build up due to heat, and it may rupture if pressure relief devices
should fail to function.
Hazardous Combustion Products:
Sensitivity To Static Discharge:
Possible, container should be grounded.
Sensitivity To Mechanical Impact:
06. ACCIDENTAL RELEASE MEASURES
Evacuate the immediate area. Eliminate any possible sources of ignition, and
provide maximum explosion-proof ventilation. Shut off source of propane, if
possible. If leaking from cylinder, or valve, contact your supplier. Never enter a
confined space or other area where the concentration is greater than 10% of the
lower flammable limit which is 0.22%.
07. HANDLING AND STORAGE
Specific requirements are listed in NFPA 58. Cylinder storage locations should be
well-protected, well-ventilated, dry, and separated from combustible materials.
Cylinders should never knowingly be allowed to reach a temperature exceeding
125°F (52°C). Cylinders of propane should be separated from oxygen cylinders or
other oxidizers by a minimum distance of 20 ft., or by a barrier of non-combustible
material at least 5 ft. high having a fire resistance rating of at least ½ hour. Full and
empty cylinders should be segregated. Use a first-in, first-out inventory system to
prevent full containers from being stored for long periods of time.
Cylinders should be stored upright with valve protection cap in place and firmly
secured to prevent falling or being knocked over. Protect cylinders from physical
damage; do not drag, roll, slide or drop. Use a suitable hand truck for cylinder
movement. Post "No Smoking or Open Flames" signs in the storage areas. There
should be no sources of ignition. All electrical equipment should be explosion proof
in the storage and use areas. Storage areas must meet national electric codes for
class 1 hazardous areas.
Propane is heavier than air and may collect in low areas that are without proper
ventilation. Leak check system with leak detection solution, never with flame. If
user experiences difficulty operating cylinder valve, discontinue use and contact
supplier. Never insert an object (e.g., wrench, screwdriver, pry bar, etc.) into valve
cap openings. Doing so may damage valve, causing a leak to occur. Use an
adjustable strap wrench to remove over-tight or rusted caps. Non-sparking tools
should be used. Never strike an arc on a compressed gas cylinder or make a
cylinder a part of an electrical circuit. Electrically bond and ground cylinder when
transferring liquid product. For additional precautions in using propane see Section
16 - Other Information.
08. EXPOSURE CONTROLS - PERSONAL PROTECTION
Natural or mechanical to prevent accumulation in worker's breathing zone above
exposure limits. (See Section 2).
Personal Protective Equipment (PPE):
Cotton Clothing is recommended for use to prevent static electric buildup.
Safety glasses are recommended when handling cylinders.
Safety shoes are recommended when handling cylinders.
Work gloves are recommended when handling cylinders.
None required in general use.
Self-contained breathing apparatus (SCBA) or positive pressure airline with mask
are to be used in oxygen-deficient atmosphere. Respirators will not function.
Before entering area, you must check for flammable and oxygen deficient
09. PHYSICAL AND CHEMICAL PROPERTIES
Unodorized propane has a slightly sweet odor. If an odorant has been added it will
have a strong unpleasant odor.

interesting that the autoignite temp is lower on propane than some of the temps that a catalytic converter can get to. doh... rock shears off propane regulator... propane spills out... next thing ya know you're saying "hey, u smell something... 2 secs later... BOOOOOOOOM!!!!! /forums/images/graemlins/shocked.gif
Hey jeffro calm down it isnt as dangerous as you think. Why would the guys on trucks put it in there truck if it was so dangerous and plus i have never seen or heard of fatality's or trucks blowin up
I Ain't Skeered!! Hell At the bus shop where I work we work with liquified natural gas. Pretty cool stuff. Liquified at 200 something below zero. Kinda cool to play with but you don't want to get much on your skin. It'll freeze-dry you.
i agree that you dont hear about propane rigs blowing up all the time. At the same time, not to many hardcore 4x4s run propane. As far as being flammable goes, propane is one of the more dangerous gases that are commonly available. If mixed with air in the right proportions and then ignited, say goodnight, cause it wont just be a little flame, it'll be an explosion.
all of that said, some peeps run it and it seems to work for them so charge on. I wouldnt run it, but thats my rig. On your rig you can run whateva u want. /forums/images/graemlins/laugh.gif
Maybe not too many rigs use propane, but I've seen some hardcore TTC compeditors that do.
What kind of carb do you need to use? I checked out the propane site but he got his for free so I'm just not seeing it.
from what I have heard you get less power. Less mileage. it costs less per gallon but not that much less. Availability is far less especially for a down the highway venture. All things concerned its a bad idea. This is what I have been told. Years ago propane was considerably cheaper which help to offset the mileage loss.
